Leviticus 23:2,3

If we pass from -say unto them" (Leviticus 23:2) to -These are," etc. (Leviticus 23:4), we perceive that the intermediate words have the air of an insertion by a reviser, writing in the spirit of P, and desiring to attain completeness by including the weekly sabbath with its -holy convocation." This inference is supported by the form of the subscription, where (Leviticus 23:38) the words, -Beside the sabbaths of the Lord," etc., have somewhat the air of an addition to the summarized description of the feasts (Leviticus 23:38) which have been enumerated.

an holy convocation i.e. an assembly called together at the sanctuary for religious purposes. They were summoned (cp. Leviticus 23:24) according to Numbers 10:2 (where -calling" is in the original identical with the word here rendered -convocation") by blowing of trumpets, cp. the Mohammedan custom, by which the muezzinsummons the faithful to prayer from the top of a mosque. The expression found here occurs outside this ch. only in Exodus 12:16, and in the directions for the observance of festival days in Numbers 28:18; Numbers 28:25 f., Numbers 29:1; Numbers 29:7; Numbers 29:12 (all P).
